AIR-CIRCULATING MECHANISIVI FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 467,195, dated January 19, 1892.

Application tiled October l, 189.1. Serial No. 407,46?. (No model.)

To all whom 'it may concern:

Be it known that we, GEORGE R. PERRY and WILLIAM H. PERRY, citizens of the United States, residing at Concord, in the county of Merrimac and State of New Hampshire, have invented certain new and useful Improvements in Air-Circulating Mechanism for Railway-Cars; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide means for a thorough distribution of the air entering the ventilators in the roof of a car.

The invention consists in a series of reciprocating fans hung upon the inner side of said roof; and it further consists in actuating mechanism located at either en d of a car and driven bythe action of the outer air while a train is in motion.

Similar reference-letters designate like parts throughout the various views of the drawings. v

The invention will be fully set forth in the following specication and claims, and clearly illustrated in the accompanying` drawings, forming a part thereof, in which- Figure l represents in dotted lines a car, showing the roof and our improvements applied thereto in longitudinal section. Fig. 2 is an enlarged end elevation of a car, showing our improved air-receiving funnels, one at each end. Fig. 3 shows a cross-section of the roof of a car provided with our improved air-circulating device and the lines of the car-body carried down in dotted projection. Fig. 4 is an enlarged broken view showing a detached portion of our air-circulating mechanism. Fig. 5 is an elevation of the driving mechanism, showing a portion of its inclosure in broken section.

A is the body of a car; B, the roof; C, the compartments at either end, in which is located an air-receiving box D, containing an air-actuated motor-wheel E, the axle e of which is mounted in said box D, one end extending through the same and carrying a crank F. A driving bar G connects said crank with a connecting -rod H, which connects with and transmits motion to the several reciprocal fans I, carried in the supports J, secured to the car-roof. Funnels K are arranged, one at each end of a car, passing through the roof and entering the air-box D ata proper location to conduct the air directly upon the motor-wheel E, after which said air is discharged through the outlet L. The throat of the f unnelsK may be provided with a valve 7c, by which the speed of the motorwheels E maybe regulated or entirely stopped, the valve at the rear of a oar being always closed and the driving-bar G detached from the rod H while the opposite motor-wheel E is driving the reciprocal fans I in the car. This valve 7o may consist in a simple slide, as shown in the enlarged view, Fig. 4, provided with a pull-cord 7c having a ring k2 attached to its lower end, and at the opposite end of said valve one or more helical springs k3 may be attached in a manner to hold said slide normally closed.

Having described our invention, whatwe claim is- 1. In a car-roof, a series of reciprocating fans, a rod running lengthwise of said roof and pivotally connected to each of said fans, air-compartments C, located one at each end of said` roof, having an air-inlet orifice provided with a funnel K and a discharge-orifice provided with a pipe L, air-actuated motorwheels mounted, one in each compartment, upon a suitable driving-shaft passing through one side of said compartment, a crank mounted upon the projecting end of said shaft, and a drivingbar connecting said cranks with the ends of the rod H, al1 substantially for the purpose set forth.

2. An air-circulating apparatus for cars, comprising a series of reciprocating fans mounted in the car-roof, a rod running lengthwise of said roof and pivotally connected to each of said fans,'a driving-bar connecting either end of said rod with the crank of a shaft e, mounted in a compartment C at each end of the car-roof, having suitable air inlet :ind discharge orifices, `and an air-zietuated mo- In testimony whereof we nix ou r si gn situ res tor-Wheel mounted upon each of said shafts e in presence of two Witnesses. within the said compartment C, and a suit- GEORGE R.
